LATCH.

SPECIFICATION forming part of Letters Patent No. 669,008, dated February 26, 1901.

Application filed July 9,1900. Serial No. 22,991. (No model.)

To all whom it may concern:

Be it known that LROBERT FRANKEN,a citizen of the United States of America, and a resident of Los Angeles, in the county of Los Angeles and State of Oalifornia,have invented certain new and useful Improvements in Door or Niudow Latches, of which the following is a specification.

My invention relates to improvements in door or window latches; and the object of my invention is the provision of an extremely sim ple, inexpensive, durable, and practical device of this character which will be easy to operate in latching and releasing and which will be reliable and efficient for the intended purpose.

To attain the desired object, my invention consists of a door or window latch embodying novel features of construction and combination of parts,substantially as disclosed herein.

Figure 1 represents a perspective View of my improved latch in locked position. Fig. 2 represents a similar view with the parts in the position assumed when released or unlatched, and Fig. 3 represents a central sectional view.

In the drawings, A designates a door-frame, and B designates a door, hinged in the frame in the well-known and usual manner and in connection with which or with a window I employ my improved latch.

One member of the latch is a spring device which forms the latch and is connected to the door or window and is made from a single piece of wire bent to form the eyes 0, which receive the fastening means, the coils O, which form the springs, and the keeper or bail O and to the frame is connected the plate D,provided with the ears D,whioh are formed with the round or cam face D and pivoted to the ear or cars is the latch E, provided with the upper cam-face E, which is in the same line or curve with the cam-face D and the latch is further provided with the notch orshoulder D with which engages the springbail C and with the handle D, adjacent to the shoulder, and by means of the handle the cam-shaped latch can be moved to release the spring-bail from engagement with the notch.

In operation when the door or window is closed the spring-bail rides up on the camfaces of the ears and latch and drops by the action of the springs into the notch or shoulder of the latch and forms a reliable hold, and to release the spring-bail to permit the door or window to be opened the handle of the latch is pressed against, which turns the latch and moves the spring-bail away from engagement with the notch, and thus releases the latch, as is evident.

The advantages of my latch are its extreme simplicity, ease of operation, inexpensiveness, and durability, and thorough efficiency for the purpose desired.

I claim- 1. In a door or window latch, the combination of the base-plate, the pivoted latch or dog having the notch or recess and the handle portion, and the spring bail or keeper adapted to ride up on the latch and spring into the notch thereof to form a latch.

2. In a door or window latch, the combination of a base plate having an ear or ears formed with a cam-face, a dog or latch pivoted to the ear or ears and having a cam-face in line with the cam-face of the ear or cars and further provided with a notch, and a spring keeper or bail adapted to ride up on the cam-faces of the ear and latch and spring into the notch of the latch to form the latch. Signed at Los Angeles, California, this 8th day of June, 1900.

ROBERT FRANKEN.
